I'm writing simple code in C using OpenSSL to generate valid bitcoin address - private key pair. I'm using this snippet to generate public key from given hex-form private key: #include. Does generating multiple public addresses from the same private key create a secuirity risk? I've recently been trying to understand the secuirity behind bitcoin public and private addresses. I have discovered that one may generate multiple different public addresses for any given private key.

Modern cryptocurrency wallets should use hierarchical deterministic (HD) keys instead.
![]() Introduction
btckeygenie is a standalone Bitcoin keypair/address generator written in Go.btckeygenie generates an ECDSA secp256k1 keypair, dumps the public key incompressed and uncompressed Bitcoin address, hexadecimal, and base64 formats,and dumps the private key in Wallet Import Format (WIF), Wallet Import FormatCompressed (WIFC), hexadecimal, and base64 formats.
btckeygenie includes a lightweight Go package called btckey to easily generatekeypairs, and convert them between compressed and uncompressed varieties ofBitcoin Address, Wallet Import Format, and raw bytes.

Addressgen is a utility to generate private keys and their correspondingaddresses for cryptocurrencies based on secp256k1. Currently, only Bitcoin,Dogecoin, and Litecoin are supported, but in the future I will add support formore.
Addressgen is tested on Linux and Windows, requires Python 3.3 and a copy oflibeay32.dll (Windows, obtained from OpensSL packages) or libssl.so (linux,openssl package).
